 There are a few things to note in this description.  First is that we are running the ```kubernetes/cassandra``` image.  This is a standard Cassandra installation on top of Debian.  However it also adds a custom [```SeedProvider```](https://svn.apache.org/repos/asf/cassandra/trunk/src/java/org/apache/cassandra/locator/SeedProvider.java) to Cassandra.  In Cassandra, a ```SeedProvider``` bootstraps the gossip protocol that Cassandra uses to find other nodes.  The ```KubernetesSeedProvider``` discovers the Kubernetes API Server using the built in Kubernetes discovery service, and then uses the Kubernetes API to find new nodes (more on this later)
 
-You may also note that we are setting some Cassandra parameters (```MAX_HEAP_SIZE``` and ```HEAP_NEWSIZE```).  We also tell Kubernetes that the container exposes both the ```CQL``` and ```Thrift``` API ports.  Finally, we tell the cluster manager that we need 1 cpu (1 core).

 Given this configuration, we can create the pod from a file specification as follows
